Amazon's PC digital distribution service has a few Double Fine titles on discount this week. Psychonauts -- the original Inception -- is available for $3.99, Costume Quest is a treat at a mere $2.99 and you can nest at ease with Stacking at $7.49.

If you've yet to play or own any of these games (for shame!), then pick 'em all up for $10 with the "Oh So Fine" bundle.
